Description

[0001] METHOD, APPARATUS AND SYSTEM FOR IMPLEMENTING CARRIER AGGREGATION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication technology, and more particularly, to a carrier combining method, a corresponding base station, a mobile terminal and a carrier combining system.

A later upgrade version of 3GPP Long Term Evolution (LTE) is called LTE-Advanced (LTE-A), and as a key technology to support wider bandwidth transmission in many new technologies introduced, carrier aggregation ) Technology is also introduced. The basic principle of carrier coupling is to satisfy two or more of the basic carrier to operate in combination to satisfy a wider bandwidth requirement. After the introduction of the carrier wave combining technique, the number of carriers of one cell varies from one to a plurality, forming a multicarrier communication scenario. At the 3GPP RAN1 # 57bis meeting, these carriers are classified into three types: a backward compatible carrier, an LTE-A dedicated carrier, and an auxiliary carrier.

1. Backward Compatibility Carrier: The LTE-A terminal can use this carrier as a carrier to be combined.

2. Carrier dedicated to LTE-A: An LTE-A terminal can not access but can access the LTE-A terminal, and the LTE-A terminal can use this carrier as a carrier to be combined.

3. Auxiliary carrier: An LTE-A terminal is a carrier that can not be accessed by an LTE R8 terminal but is accessible under certain conditions. As an access condition, when the terminal has already established a communication connection through a downlink-compatible carrier wave or an LTE-A dedicated carrier wave, the terminal can use the auxiliary carrier wave as a separate carrier wave when performing carrier combining. That is, the auxiliary carrier may be used only in the case of a terminal in which communication is established on at least two and more carriers, and the carrier operating the terminal that established communication on one carrier can not be an auxiliary carrier file.

Currently, LTE-A is classified into two operation modes: time division duplex (TDD) and frequency division duplex (FDD). Correspondingly, a mobile terminal operating in the TDD mode is referred to as a TDD terminal, and a mobile terminal operating in the FDD mode is referred to as an FDD terminal. Likewise, carriers applied to the TDD operation mode are subjected to TDD conveyance, and carriers applied to the FDD operation mode are conveyed to the FDD conveyance mode.

In the prior art, a relatively mature implementation method has not been found yet in terms of how to perform carrier wave combining. The industry has already proposed a carrier combining method that combines a TDD carrier to a TDD terminal and an FDD carrier to an FDD terminal, but has not yet determined a concrete implementation plan. In addition, carrier combining in different modes can not be realized, i.e., the FDD carrier can not be coupled to the TDD terminal and the TDD carrier can not be coupled to the FDD terminal.

An embodiment of the present invention provides a method of performing a carrier wave combining, a corresponding base station, a mobile terminal, and a carrier wave combining system so that both a TDD terminal and an FDD terminal can combine a TDD carrier and an FDD carrier.

A method for performing a carrier combination according to an embodiment of the present invention includes:

Wherein the mobile terminal establishing the connection receives the carrier combination control information transmitted from the base station, wherein the carrier combination control information includes a carrier identifier of a target carrier to be combined as a downlink operation carrier and wireless resource allocation information of the target carrier do; And

And the mobile terminal establishing a target carrier using the carrier identifier and the radio resource allocation information.

A base station according to an embodiment of the present invention includes:

And carrier-combining function means for transmitting carrier-combining control information to the mobile terminal establishing the connection

The carrier combination control information includes a carrier identifier of a target carrier to be combined as a downlink operation carrier and radio resource allocation information of the target carrier.

A mobile terminal according to an embodiment of the present invention includes:

A connection establishing means for establishing a connection with the base station,

Receiving means for receiving the carrier combination control information transmitted from the base station The carrier combining control information includes a carrier identifier of a target carrier to be combined as a downlink operation carrier and radio resource allocation information of the target carrier;

And carrier coupling performing means for determining a target carrier based on the carrier identifier and the radio resource allocation information.

In the carrier coupling performing system according to the embodiment of the present invention,

Wherein the carrier combination control information includes a carrier identifier of a target carrier to be combined as a downlink operation carrier and radio resource allocation information of the target carrier;

And a mobile terminal for receiving the carrier combination control information transmitted from the base station and for determining the target carrier according to the carrier identifier and the radio resource allocation information.

According to the present invention, the carrier combination control information is transmitted by a base station to a mobile terminal (the mobile terminal may be a TDD terminal and may be an FDD terminal), and the carrier combination control information includes a carrier wave of a target carrier to be combined as a downlink operation carrier Identifier and radio resource allocation information of the target carrier. The mobile terminal determines the target carrier (the target carrier can be a TDD carrier or an FDD carrier file and carries data according to its operation mode regardless of whether the target carrier is a TDD carrier or an FDD carrier) according to the carrier identifier and the radio resource allocation information do. According to the above method, it is not necessary to classify the operation mode of the mobile terminal as well as the operation mode of the target carrier (that is, it is not necessary to distinguish whether the target carrier is the TDD carrier or the FDD carrier) It is not necessary to distinguish between the terminal and the FDD terminal), so that the carrier combination under the same mode and different modes can be easily performed.

FIG. 1 is a flowchart illustrating steps of a method for performing a carrier combination according to an embodiment of the present invention.
2 is a diagram illustrating a configuration of a base station according to an embodiment of the present invention.
3 is a diagram illustrating a configuration of a mobile terminal according to an embodiment of the present invention.

In the carrier combining method according to the embodiment of the present invention, both the TDD terminal and the FDD terminal can combine the TDD carrier and the FDD carrier.

Hereinafter, a method of performing a carrier combination according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a flowchart illustrating steps of a method for performing a carrier combination according to an embodiment of the present invention. The method includes steps S101, S102, S103, and S104.

In step S101, the mobile terminal establishing the connection receives the carrier combination control information transmitted from the base station.

The carrier combination control information includes the carrier identifier of the target carrier to be combined as the downlink operation carrier and the radio resource allocation information of the target carrier.

In step S102, the mobile terminal confirms the target carrier by the carrier identifier and the radio resource allocation information, and monitors the downlink control channel of the target carrier.

In step S103, the mobile station parses the downlink control information of the Cell-Radio Network Temporary Identifier (C-RNTI) for the mobile terminal on the downlink control channel of the target carrier.

In step S104, the mobile terminal acquires the downlink data transmitted from the base station to the mobile terminal on the downlink shared channel by the downlink control information of the parsed C-RNTI.

Hereinafter, each step will be described in detail.

Prior to step S101, the mobile terminal and the base station of the LTE-A establish a Radio Resource Controller (RRC) connection and conduct communication. Here, the TDD terminal accesses the TDD carrier to proceed with communication, and the FDD terminal accesses the FDD carrier to proceed with communication. When the base station eNB allocates the mobile terminal to perform the carrier combining operation, it transmits carrier combination control information to the mobile terminal to add the downlink FDD carrier or the downlink TDD carrier through the carrier combination Demand. In step S101, the mobile terminal receives the carrier combination control information transmitted from the base station, and the carrier combination control information includes the carrier identifier of the target carrier to be combined as the downlink operation carrier and the radio resource allocation information of the target carrier. In a specific application, the carrier identifier of the target carrier and the radio resource allocation information of the target carrier may be transmitted to the mobile terminal in various manners. For example:

In case of carrying the carrier identifier of the target carrier and the radio resource allocation information of the target carrier using the control signaling of the RRC layer, the corresponding control signaling established according to the format of the RRC control signaling of the current 3GPP 36.331 includes the frequency point of the target carrier, , A physical HARQ indicator channel (PHICH) allocation, a system frame number (a system frame number may not be included if a target carrier and a carrier wave of the mobile terminal are frame-synchronized), a monitoring start frame The monitoring start frame information may not be included when the interval time length is applied) and wireless resource allocation information. In another example, the RRC control signaling may include a target carrier number, a monitoring start frame, and radio resource allocation information. Here, the radio resource allocation includes information such as a downlink shared channel allocation, an uplink control channel allocation, an uplink shared channel allocation, an uplink power control, a channel condition feedback report allocation, and an antenna situation allocation. The above description is merely an example, and the carrier identifier of the target carrier and the radio resource allocation information of the target carrier may be transmitted to the mobile terminal using another signaling format, but the present invention is not limited thereto.

At the same time, the eNB transmits the carrier combination control information to the mobile terminal, and then schedules the mobile terminal through a target carrier (downlink FDD carrier or TDD carrier) within a prescribed time period. A system information-radio network temporary identifier (SI-RNTI), a paging-radio network temporary identifier (P-RNTI) and the like, through a downlink control channel of a target carrier (Cell-Radio Network Temporary Identifier, C-RNTI) of the cell-radio network for the mobile station. The target carrier to be combined as a downlink operation carrier carries the corresponding data according to its own operation mode and the scheduling instruction of the eNB without any change. That is, when the target carrier wave is the FDD carrier, the FDD carrier to be combined as the downlink operation carrier does not know whether the corresponding data stored in the FDD carrier is transmitted to the TDD terminal or the FDD terminal. Similarly, when the target carrier wave is a TDD carrier, it is unknown whether the corresponding data on the TDD carrier to be combined as the downlink operation carrier is transmitted to the TDD terminal or the FDD terminal.

In step S102, the mobile station determines the target carrier by monitoring the received downlink control channel of the target carrier based on the received carrier identifier and the radio resource allocation information.

There are two types of monitoring operation of the mobile terminal: explicit indication and implicit indication.

In the explicit indication scheme, the base station further includes monitoring start indication information in the carrier combination control information of the mobile terminal transmitted by the base station. When the mobile terminal determines that the monitoring start timing is reached according to the received monitoring start indication information, And monitors the downlink control channel of the carrier. Here, the monitoring start instruction information can indicate the time length of the monitoring interval, that is, the mobile station instructs to start monitoring after a time interval of X ms after receiving the carrier combination control information. Alternatively, the monitoring start instruction information can indicate a monitoring start frame, and instructs the mobile station to monitor the downlink control channel of the target carrier at the timing corresponding to the monitoring start frame.

For implicit indication, the length of time of the monitoring interval is predetermined between the base station and the mobile terminal in advance. After receiving the carrier combination control information transmitted from the base station, the mobile station starts monitoring the downlink control channel of the target carrier when it is determined that the mobile station has reached the time length of the predetermined monitoring interval with the base station.

In step S103, the mobile terminal parses the downlink control information for the present mobile terminal C-RNTI, which is placed on the downlink control channel of the target carrier. However, the downlink control information of the SI-RNTI and the P-RNTI is not parsed. This ensures that the mobile terminal only uses the target carrier as the auxiliary carrier.

In step S104, the mobile terminal acquires the downlink data transmitted from the base station to the mobile terminal on the downlink shared channel, based on the downlink control information of the parsed C-RNTI.

When the radio resource allocation information of the target carrier is changed, the base station informs the mobile terminal of the changed radio resource allocation information and notifies the mobile terminal of the changed radio resource allocation information according to the changed radio resource allocation situation Allow the data to be received normally. The changed radio resource allocation information of the target carrier may be notified to the mobile terminal or may be placed in the RRC control signaling.

The base station only needs to transmit the carrier combination retirement indication information including the carrier identifier of the target carrier to the mobile terminal when the mobile terminal desires to exit the target carrier. This carrier combination exit indication information may be included in the RRC control signaling, or may be transmitted to the mobile terminal in other manners. After receiving the carrier combination retirement indication information transmitted by the base station, the mobile station stops monitoring the downlink control channel of the target carrier.

The configuration of the base station according to the embodiment of the present invention based on the same inventive idea has the carrier coupling function means 21 as shown in FIG.

The carrier wave combining function means 21 transmits the carrier wave combining control information to the mobile terminal. Here, the carrier combination control information includes the carrier identifier of the target carrier to be combined as the downlink operation carrier and the radio resource allocation information of the target carrier.

In one embodiment, the base station includes scheduling means for loading downlink control information of the C-RNTI of the mobile station on the downlink control channel of the target carrier and loading downlink data to be transmitted to the mobile station on the downlink shared channel 22).

In one embodiment, the carrier coupling function means 21 also notifies the mobile terminal of the changed radio resource allocation information when the radio resource allocation information of the target carrier is changed.

In one embodiment, the carrier combining function unit 21 also transmits carrier combination retirement indication information including the carrier identifier of the target carrier to the mobile terminal, and causes the mobile terminal to monitor the downlink control channel of the target carrier ; To the scheduling means (22).

The scheduling means 22 also receives the carrier combination release notification transmitted from the carrier combination function means 21 and stops loading the downlink control information of the C-RNTI of the mobile station on the downlink control channel of the target carrier .

The configuration of a mobile terminal according to an embodiment of the present invention based on the same inventive idea includes a connection establishment means 31, a reception means 32 and a carrier combination means 33 as shown in FIG.

The connection establishment means 31 establishes communication access with the base station.

The receiving means 32 receives the carrier combination control information transmitted from the base station. Here, the carrier combination control information includes the carrier identifier of the target carrier to be combined as the downlink operation carrier and the radio resource allocation information of the target carrier.

The carrier combination performing means 33 determines the target carrier by the carrier identifier and the radio resource allocation information.

In one embodiment, the carrier combination performing means 33 further monitors the downlink control channel of the target carrier and parses the downlink control information of the C-RNTI of the present mobile terminal and transmits the parsed C-RNTI down And obtains the downlink data transmitted to the mobile terminal from the base station in the downlink shared channel by the link control information.

In one embodiment, the receiving means 32 also receives the modified radio resource allocation information of the target carrier transmitted from the base station and delivers it to the carrier combination performing means 33.

The carrier combination performing means 33 also monitors the downlink control channel of the target carrier according to the carrier identifier and the changed radio resource allocation information.

In one embodiment, the receiving means 32 also receives the carrier combination retirement indication information including the carrier identifier of the target carrier transmitted from the base station and delivers it to the carrier combination performing means 33.

The carrier combination performing means 33 also stops monitoring the downlink control channel of the target carrier after receiving the carrier combination withdrawal indication information.

The carrier combining system according to an embodiment of the present invention based on the same inventive idea includes a base station and a mobile terminal.

The base station transmits the carrier wave combining control information to the terminal establishing the connection. The carrier combination control information transmits the carrier identifier of the target carrier to be combined with the radio resource allocation information of the target carrier as the downlink operation carrier.

The mobile terminal receives the carrier combination control information transmitted from the base station, and determines the target carrier based on the carrier identifier and the radio resource allocation information.
